“It was a crazy time. It's sort of like a dream I couldn't wake up from,” he told E! News. “It was a runaway train I couldn't get off of, and I was the conductor. It's something that could never happen again, so that's pretty cool."

Sheen took the experience and made it a good one. He felt that he could do anything at the time, and learned that wasn’t necessarily true.

"I learned a lot. I learned stick to what you know,” he said. “I learned, don't go on a one-man show to 21 cities with no act. My life's different now that I'm not insane anymore. I'm accountable most of the time."

His show Anger Management has a big future too. FX president John Landgraf announced the show will probably get picked up for 90-episodes, a run that FX generally decides on after the first 10 episodes air.

Sheen talked about whether 90 episodes makes him nervous at all, or if he was prepared for it.

"It doesn't put any pressure on me,” he told E! News. “That's something we can't control...[It's] exciting as hell. I don't think 90 is going to be enough. I said that out loud, didn't I? I feel like how we've started, we've just scratched the surface."

If the show is picked up for those episodes, they have announced that Martin Sheen, Charlie’s father, will be added to the show as a series regular.

The elder Sheen appeared in an episode in the first season of the show.

"I think it's the best episode we did,” said Charlie. “That was the last one we shot. So I don't want to say we peaked, but he brings a whole different energy to it."

Another familiar face may be making an appearance this season too. Denise Richards, Charlie Sheen’s ex-wife, also made a guest appearance on the first season.

"We had a ball working on the show,” he said. “She was fabulous on the show. She'll probably come back and she's welcome back."

There is a second reason for having Richards on the show also, one that may help the show out in the long run.

"She did a great job,” said executive director Bruce Helford. “It was really nice to have Charlie's family on the set."
